Gisele Bundchen is back with H&M as the face of their Summer 2014 campaign. Following her recording debut of ‘All Day And All Of The Night’by The Kinks in H&M’s Fall/Winter 2013 campaign, Bundchen will again provide not only the looks but the vocals for the brand this summer. The supermodel is teaming up with French house music producer Bob Sinclair to record an original take on Blondie‘s ‘Heart of Glass,’ set to debut complete with an official music video in May. The song will be available free on H&M’s website or for download on iTunes. All proceeds from the sale of her single will go to UNICEF.
